Two new species of the damselfly genus Euphaea Selys, 1840 (Odonata: Euphaeidae) are described from the Western Ghats of Satara District, Maharashtra, distinguished by their distinct morphology and coloration. E. thosegharensis Sadasivan & Bhakare sp. nov. is similar to E. cardinalis (Fraser, 1924), but is distinguished by the extensor and flexor surface of all femora black while all femora bright red in E. cardinalis; apical fourth of Hw black while apical half of Hw black in E. cardinalis; genae reddish-orange, black in E. cardinalis; a tuft of sparse stub black hair on either side of tergite of S9 while both S8 and S9 with tufts of long ventral hairs in E. cardinalis.  Male genital vesicle matt black, with distal border rounded angles, while vesicle black and hexagonal in shape with rounded angles in E. cardinalis and S9 twice the length of S10, while S9 and S10 of equal length in E. cardinalis. E. pseudodispar Sadasivan & Bhakare sp. nov., is very close to E. dispar (Rambur, 1842), but is differentiated easily by the absence of yellow patch on legs as in E. dispar; only apical fifth of Hw black; genae being yellowish-white, while black in E. dispar; male genital vesicle brownish-black & rhomboid-shaped and with no transverse rugosities while black with distal border rounded and with fine transverse rugosities in E. dispar; penis with single seta on each side while E. dispar has three pairs; sternite of S9 very prominently extending ventrally like a beak in comparison with E. dispar.  We have identified additional morphological characters useful in taxonomy of Euphaea of the Western Ghats for example, tufts of ventral hairs on terminal abdominal segments genital vesicle, penile structure of males and sternite of S9 in the males, and vulvar scales of females.  A taxonomic key to all known species of genus Euphaea of the Western Ghats is also provided.

Acid Administration

We observed that on long-term breeding, gp91phox-knockout (gp91phox−/−) mice developed white hair. Here, we investigate the origin of this hitherto unexplained phenomenon. Moreover, we investigated the effect of tranexamic acid administration on the hair color in gp91phox−/− mice. We administered tranexamic acid (about 12 mg/kg/day) orally to 9-week-old C57BL/6j (control) and gp91phox−/− mice, thrice a week for 12 months. Compared to control mice, gp91phox−/− mice showed more white hair. However, the concentrations of reactive oxygen species and the levels of interleukin (IL)-1β and transforming growth factor (TGF)-β in the skin were lower than those in the control group. Furthermore, increase in white hair was observed in the control mice upon administration of the IL-1β antagonist. On the other hand, administration of tranexamic acid led to brown colored hair on gp91phox−/− mice. Although tranexamic acid treatment did not alter the expression levels of melanocortin receptor 1 and agouti signaling protein on hair follicles, it increased the expression of mahogunin ring finger protein 1 (MGRN1) and collagen XVII. These results suggested that retention of black hair requires the gp91phox/ROS/IL-1β/TGF-β pathway and that elevated levels of MGRN1 and collagen XVII lead to brown hair in gp91phox−/− mice.

Face thickly clothed with pale yellowish-white hair, on the sides mixed with black. Vertex clothed with yellowish-white hair, which is fringed in front with black. Cheeks clothed with brownish-black, sometimes slightly mixed with whitish, hair. Clypeus shining, sparsely punctured, labrum fringed on free edge with rusty yellorv hair. Clothing of thorax above and on sides yellowish white, mixed with black in front of insertion of wings. A broad patch of black berween the wings surrounds the smooth, polished mesothoracic disc and extends back in a point over the middle of metathorax. On each side of metathorax is a tuft of yellowish white bair.

The temperature calibration for cool stars and in particular the Miras continues to be contentious. Lunar occultations have provided radii for many K and M stars and a good temperature calibration has been derived for the hotter non-variable M stars (Ridgway et al. 1980). The situation for the Miras and carbon stars and the metal-rich and metal-poor M stars is, however, not so clear cut. Observations are generally made in some broad-band color such as (R-I), (V-K) or (J-K) and a temperature derived using either the Ridgway et al. (1980) empirical scale or a black-body scale; differences can amount to several hundred degrees. We decided to theoretically explore the effects that extension, metallicity and pulsation could have on colors.

History Of

Cytogenetic analysis is an important step in the diagnosis of animals with a history of infertility or sterility. While chromosomal studies have been indicated for livestock species for years, the demand for such analyzes in companion animals has recently increased. The coat color in cats known as tortoiseshell presents predominance of black hair mixed with white and orange hair all over the body and, in the color pattern known as calico, these three colors are presented as independent spots with predominance of white hair. However, all of these patterns are limited to females due to sex-linked inheritance. Male tortoiseshell or calico cats occur rarely, due to the occurrence of chromosomal aberrations. This article reports the chromosomal analysis of a male cat with tortoiseshell pelage that presented an extra X chromosome (diploid chromosome set of 2n = 39,XXY), a condition which is similar to Klinefelter syndrome in humans.
